Embodiment 1
Fig. 1 is the phantom of the fine bubble generating apparatus B in the embodiment of the present invention 1, the amplification view of Fig. 2 presentation graphs 1.
As shown in Figure 1, this fine bubble generating apparatus B, the 1st structure 1 can be rotated so that airtight conditions is relative with the 2nd structure 2, described the 1st structure 1 mainly has liquid introduction channel 3 and is located at the gas introduction channel 4 of its core, described the 2nd structure 2 mainly has the liquid from liquid introduction channel 3 is changed over to spiral flow, and can be sent near the helical form liquid introduction channel 54 outlets of gas introduction channel, the gas-liquid mixed export mouth 6 of discharging with the gas liquid mixture that the liquid by becoming spiral flow and gas from gas introduction channel 4 are formed.
Wherein, in this fine bubble generating apparatus B, as shown in Figure 1 and Figure 2, the top portion of liquid introduction channel 3 is formed by the easy interface tube 7 of peace loading, unloading (the so-called interface that touches) of pipeline, and the top portion of gas introduction channel 4 is formed by flow rate regulating valve 8.
As shown in Figure 1, the bottom of the 1st structure 1 is inserted in to the upper end of the 2nd structure 2,1st, O ring 90 is set between the 2nd structure 1,2, and to the structural walls of the 1st, the 2nd structure 1,2, squeezing into two cotter pins 91,91 (squeezes into, make at all-round formation recess 92, and make the bottom surface of recess 92 of minor diameter part and the cotter pin 91 can be with the form rotation of sliding).And above-mentioned cotter pin 91,91 also has the anti-avulsion function with respect to the 1st structure 1 of the 2nd structure 2.
The 1st structure 1 that becomes one structure and the 2nd structure 2 are being carried out to when separated, will sell 91,91 from the 1st, the 2nd structure 1,2 releases.
The 1st structure 1 as mentioned above, as shown in Figure 1 and Figure 2, has liquid introduction channel 3, gas introduction channel 4, interface tube 7 and flow rate regulating valve 8; The 2nd structure 2 has helical form liquid introduction channel 5 and gas-liquid mixed export mouth 6.
Liquid introduction channel 3, as shown in Figure 1, forms with horizontal L word shape, by the liquid entering from being connected to the pipeline t of interface tube 7, with the form guiding, extends to helical form liquid introduction channel 5 downwards.Wherein, as shown in Figure 1, described helical form liquid introduction channel 5 integral body show slightly cone shape, are the form that helical blade 51 is installed at the outer peripheral face of central solid part 50.
Therefore, the liquid entering from pipeline t, discharge in the path of liquid introduction channel 3 → helical form liquid introduction channel 5 (now becoming for the first time the spiral flow) → gas-liquid mixed export mouth 6 by interface tube 7 → horizontal L word shape.
Secondly, as shown in Figure 1 and Figure 2, gas introduction channel 4 forms with horizontal L word shape, and by the negative pressure of being discharged in the flow rate regulating valve 8 producing from gas-liquid mixed export mouth 6 by liquid, gas is inhaled into from peristome 80.
Here, in the present embodiment, the major part of gas introduction channel 4 consists of pipeline 40, and the top of this pipeline 40 can be inserted and unload on the recess 42 of screw body 41, the bottom of this pipeline 40 can be inserted and unload on the recess 52 of central solid part 50, keeps respectively the form of inserting.And, on screw body 41, by described recess 42 and than it more the diameter holes 43 of upper side form through holes, this through hole connection traffic is adjusted the gas introduction channel 4 that valve 8 forms.And, by under the state of flow rate regulating valve 8 and screw body 41 unloadings, can take out upward (contrary, also can to insert) pipeline 40, therefore, need not separated the 1st structure 1 and the 2nd structure 2, also can replace pipeline 40.And, on central fixed part 50, by above-mentioned recess 52 with than it more the diameter holes 53 of lower side form through holes, the opening portion of above-mentioned breakthrough part is relative with gas-liquid mixed export mouth 6 and put.
As shown in Figure 1 and Figure 2, interface tube 7 is the laterally extending cylindrical portion to the 1st structure 1, from the back side towards opening portion, and Inserting Tube strip of paper used for sealing 70, lining ring 71, retaining ring 72, collar 73, axle sleeve 74 and form successively.And, in this interface tube 7, pipeline t is inserted on axle sleeve 74, by retaining ring 72, make pipeline t in anti-avulsion state.And, in the situation that pipeline t is extracted out, press axle sleeve 74 claw of retaining ring 82 erected.
Flow rate regulating valve 8 is used the valve of selling on market, and the operating portion shown in Fig. 1, Fig. 2 81 is carried out to positive and negative rotation, just can freely change the gas flow sucking from peristome 80.Yet this flow rate regulating valve 8 has the pipeline linkage function identical with above-mentioned interface tube 7, but this pipeline linkage function can not yet.
And the 2nd structure 2, as shown in Figure 1, has in territory, top and expand large-diameter portion 20, and territory, bottom is formed with male screw 21, thereby described male screw 21 is screwed togather with nut 22.Here, when the 2nd structure 2 is installed to storage tank T (inside contains liquid) etc., by above-mentioned expansion large-diameter portion 20 and nut 22, storage tank T is clamped.
Then, the action of this fine bubble generating apparatus B is described.
When using this fine bubble generating apparatus B, as shown in Figure 1, to the gas-liquid mixed export mouth 6 immersion liquid of major general's the 2nd structure 2, thereby to liquid introduction channel 3 force feed fluid under pressures.
So, the fluid under pressure entering from pipeline t (now becomes spiral flow for the first time by liquid introduction channel 3 → helical form liquid introduction channel 5 of interface tube 7 → horizontal L word shape, with the gas from gas introduction channel 4 introduced becoming admixture thereafter) path of → gas-liquid mixed export mouth 6 discharges, thereby produces a large amount of micro-bubbles in the liquid in storage tank T.Yet, for the genesis mechanism of this micro-bubble, because be known, so do not do detailed discussion.
Embodiment 2
Fig. 3 represents the phantom of the fine bubble generating apparatus B in embodiments of the invention 2.
The fine bubble generating apparatus B of this embodiment 2, basic identical with above-described embodiment 1, difference is, in embodiment 1, flow rate regulating valve 8 and the 1st structure 1 are screwed togather, and in this embodiment, on the gas introduction channel 4 extending, flow rate regulating valve 8 has directly been installed.
In the fine bubble generating apparatus B of such embodiment 2, obviously can reach same function.
The all material of the 1st structure the 1, the 2nd structure 2, pipeline 40 etc., according to liquid, environment, purposes, can consist of the metals such as brass, stainless steel or various synthetic resin material.
In above-mentioned the 1st embodiment, as air inflow aperture, use flow rate regulating valve (can adjust Fluid Volume), but be not limited to this, also can use orifice plate (Fluid Volume is fixed).Main points are, as long as the top portion of gas introduction channel can adjust flow or the fixing air inflow aperture of flow.
